To all whom it may concern: i U

Be it knownithat I, ADOLPH RUBIN, v a citizen of the United Statesresiding at St. Louis, Missouri, have invented a certain new and usefulImprovement in Loose-Leaf Binders, of which the following is a full,clear, and exact description, suchas will enable others skilled in theart towhich it appertains to make and use the same. I,

This invention relates to loose leaf binders of the type which comprisetapes, bands or cords arranged. in slots in the leaves and connected toa'winding shaft that is adapted to be turned in one direction to drawthe tapes taut and-cause theleavesto be clamped securely together; bytwo cooper: at-ing leaf-clamping members, one ofwhich carries thewinding shaft. a p j One object of my presentinvention is to provide anovel locking. mechanism for the winding shaft. i v Another, ob'ect istoprovide a novel means for securing the tapesto; one of theleaf-clamping members of the-binder.

And still another object is to provide a 7 novel means for connectingthe covers of i the binder to the leaf-clamping members.

Figure 1 of the drawings is an end View of a loose leaf binderconstructed 1n ac cordance with my lnvention.

'Fig. 2 is, a vertical sectional view of the i binder,,taken on the line2 2 of Fig. j

' Fig. 3 i a horizontal-sectional view, taken on the line 3- -3 oof Fig.2.;and. p i f,

Fig. f is a sectional View, taken on'the line 4:4@ of'Fig. 3,illustrating the con- I struction of the clips that are used forconnecting the ends of the tapes to one of the leaf-clamping members.-

Referring to the drawings which illustrate the preferred form of myinvention, A and A designate two leaf-clamping members between which therear edge portions of the leaves B are arranged, C designates tapes,bands or cord of flexible material that pass through slots in saidleaves and in said leaf-clamping members and D designates a windingshaft to'which one end of the tapes C are connected, the opposite endsof said tapes being connected to a flange l on the leaf-clamping memberA and said winding shaft being provided at one end with a finger piece Dby which it'can be turned. 7

nected to the winding shaft and arranged v the spring 3 is; alaterally-projecting:arm

5'. provided with an extension 6 and at the opposite end of said springis a laterally projecting arm .5? provided with; an exten: sion 6*. Theextension 6 of the arm at the lower end of the torsion spring cooperateswith theratchet. wheel 2, and theexterrsion 6f of the arm at the upperend of saidtorsion spring projects into the-upper end, of

a tubular-shaped part 7 on the leaf-clamping member A. A winding shaftlocking mechanism of the construction .abofve jde scribed can bemanufactured at a. low cost; it will not wear out quickly on accountpfthe fact that the spring. of same is a torsion.

spring that will retain its, resiliency even after long continuous use,and still another desirable feature of such a lockingfmecha-Q nism isthat the spring of same is of such a character that iteffectivelypreventslthe shaft from being turned in one direction andstill does not ofler considerable resistance to the shaft when it isbeing turned in a direction to tighten the tapes, thereby enabling thewinding shaft to be manipulated easily. i

The covers E of the binder are connected to the leaf-clamping members byflexible hinges, each of which is formed from a piece of fabric, leatheror other pliable material 8 connected at one edge to its cooperatingcover and having its opposite edge portion arranged in thetubular-shaped portion 7 on the leaf-clamping member with which itcooperates. The edge portion of the flexible hinge member 8 that isconnected to the leafclamping member is preferably provided ,tion 7,previously referred to;

with a 'bead that is snugly surrounded by the tubular-shaped portion 7on the leafclamplng member. One convenlent and 1nexpensive way ofconnecting the hinge members 8 to the leaf-clamping members is to form abead on the edge'portion ofeach 0t said hinge members by means of apiece of.

can be manufactured at a low cost, and

there is little liability of its being acciden tally detached from theleaf-clamping member to which it secured, owing to the fact that; itis'pr'ovided at one edge with a' bead that is completely surround'edby aportion on the least-clamping member that is bent oversamei 1Thetape's'C are connected' to the flange I on the leaf clamping member Aby means of clips 10, as shown in'Fig; 3, each of which consists of asubstantially U-shapecl member, formed from sheet metal, that is slippedover the end portion of the tape after the tape has been lapped over orwra ed around the flan e 1 as shownin Fig. 3. Said clips '10 areconnected to the flange- 1, preferably by pressing portions II of eachclip into holes 1 2 in the flange, as shown in Fig. 4, thereby producinganeflicient' and inexpensive means for securing the tapes to theleaf-clamping member A ofthebinder. it

Having thus described my invention, what I claim; and desiretose'cu'reby Letters Pat'- ent, is: 1 loose leaf binder of the type dcscribed pl'ovided with a winding shaft,"'aleaf-clamping member on whichsaid? shaft: is"rotata'bly mounted, a toothed portioir on said'shaft,and a torsion spring on-said leaf clamping member that cooperates withsaid toothed portion; to prevent the winding shaft from being turned inone direction.

2., A looseleaf binder of the type described provided with a windingshaft, "a leaf-clamping member on which said winding shaft is rotatablymounted, a ratchet said shaft, a torsion spring arranged in:bear-'--ings on said leaf clamping member and extending the entire length ofsame, a laterally projecting arm at one end of said spring provided withan extension that cooperates with said ratchet; wheel; and alaterallyprojecting arm at the opposite end of said' spring providedwith an extension that fits in an opening'iirsaid letIf' ClillnPlHg'member;

4. A loose leaf binder, comprising leafclamping members,tapes or handsthat pass through slots-in the leaves, a flange on one of saidleaf-clamping membersyand clips secured to said flange and arranged sothat they embraceportions of'said tapestha-t are wrapped around saidflange;

5.A l'o'os'e' leaf binder; comprising leafclampingmembers, one of whichis provided with a flange, tapes or bands that pass through slots in the'l'eavesand through slots in said leaf cl'ampingmembers, one" end 0teach of said tapesbeing lapped over said flange,'andsubstantially Ushaped clips arranged over theportionsof the tapes that lap over saidflange and secured to said flange by portions on said clips thatarepressed mto holes nr saidflange;
